Blue light goes out but does not flash when turning on ignition. Yellow wire connected together. Directions from other troubleshooting say the bus wires are are reversed. Do I modify the t-harness to fix this problem? I have the programmer and ref lashed the unit.

Have you tried it with the yellow wire cut? The install guide is a little confusing regarding that wire. It says cut for 2010 and less. I think they may mean 2010 and newer,

Is it normal To have no ignition lights when the t-harness is installed? The ignition key turned to ignition or on has no effect when the t-harness is installed. Please confirm, I SHOULD cut the yellow wire for a 2012 Dodge Grand Caravan?
No, ignition wire should not be cut. This modification is for 2010 and lower.

What is the voltage on your can wires ?
Thanks! I made no changes. I found the can bus pin bent in my t -harnesst. It's working now.
